1 eccentric screw drive
2 pressure valve
3 suction valve
The metering pumps ELADOS
electrical motor for industrial use.
The metering pumps are suitable for use with clean, non-abrasive metering media with
a viscosity of up to 200 mPas (measuring manner: Brookfield).
The eccentric screw drive (pos. 1) moves the membranes (pos. 5) and thus transports the
metering material via the pressure valve (pos. 2). The suction valve is closed.
The membrane is moved back using a return spring (pos. 6), by means of which the
metering material is sucked into the pump head via the suction valve (pos. 3).
The pressure valve is closed.
The transported material can only be regulated via the stroke regulator (pos. 4) during
operation. Here the return movement of the membranes is restricted.
NOTICE!
To protect the metering device, the use of a suction pipe with an empty
reporting device and dirt arrestor (available from our range of accessories) is
highly recommended! The empty reporting device switches off the pump if it
falls below a certain level (in the container). The permissible primary pressure
must always be adhered to in accordance with the table
10.3 'General data – Standard pumps' on page 55!
